Recently, feeling of safety in the residential area as a component of a proper housing has attracted a lot of attention from psycho-sociologist. Hence, this survey aims at determining the relationship between dwelling type, environmental aspects of housing welfare, and residents’ sense of insecurity in Bandar-Abbas, Iran using a self-administered structured questionnaire distributed among 384 residents (62 from single-unit houses + 322 from apartment complexes) randomly selected. The findings show that dwelling type is significantly related to sense of insecurity among the residents. Further, the relationship between the components of housing welfare in residential building and residents’ sense of insecurity is negatively significant. Additionally, regarding the effect of housing welfare components in residential neighborhood, only the access to recreational services has a significant negative but small effect on the sense of insecurity. Therefore, the factors which contribute to improved residents’ feeling of safety may absorb more attention by both designers and policy makers in the housing development in order to increase the welfare of housing.
